The fluorescent pigment dyeing process of cotton knitted fabric after cationic modification is studied. The influences of modifier and sodium hydroxide concentration, modification time and temperature on the modified effect are discussed. The influences of the surface active agent, dyeing time and temperature on the dyeing results are analyzed. The influences of adhesive concentration, the fixing time and temperature on the fixing results are discussed. The optimum process of modification is： cationic modifier 4% （omf）, sodium hydroxide 2.5 g/L, modified at 70℃,for 30 min. The optimal dyeing process is： dyeing at 60 ℃, for 20 min. The optimum fixing process is： adhesive 8% （omf）, crosslinker 1% （omf）, fixing at 70 ℃, for 20 min. The dry rubbing fastness is Grade 4N5 and the wet rubbing fastness is Grade 2N3 after fixing.
